Here is where you can get an idea of how relentless
my imagination can be. Rather than simply enjoy the
symbol for its beauty, I had to know which way was
considered the 'regular' direction for the swirls to flow.
As it turns out, when it goes "anticlockwise" it is feminine,
and the passive direction for the swirls to revolve around,
as it represents past time, and since the past has actually
happened already, it is passively there. The future awaits.
If the swirls flow "clockwise" it is considered as masculine,
and future time. So even the Yin Yang symbol (taiji or tai-ji)
can show either Yin (anticlockwise/feminine) or Yang energy,
(clockwise/masculine), and also the white is Yang, black Yin,
because black represnts all the colours combined and white
represents the absence of all colour, which is pure potential.

PS: Sorry about me incorrectly using the word "Yi Jin" for this,
but of course anyone who does as much woolgathering as I do
will ultimately start speaking in riddles, as I do even to myself.
